CARBURETER.

SPECIFICATION forming part of Letters Patent No. 768,732, dated August30, 1904. Application filed November 18, 1903. Serial No. 181,109. (Nomodel.)

To all whom it may concern:

Be it known that I, SELDoN CLARK BRUCE, a citizen of the United States,residing at the city of Goshen, county of Elkhart, and State of Indiana,have invented certain new and useful Improvements in Carbureters, ofwhich the following is a specification.

This invention relates to improvements in carbureters.

The objects of this invention are, first, to provide an improvedcarbureter in which the introduction of the air and the liquidhydrocarbon in proper proportions is automatically controlled; second,to provide an improved carbureter in which the amount of carbureted airproduced is controlled by the amount consumed; third, to provide animproved carbureter in which practically all of the liquid hydrocarbonis utilized; fourth, to provide an improved carbureter which althoughsimple and compact in structure is of large capacity and is economicalto produce and not likely to get out of repair.

Further objects and objects relating to struc- 2 5 tural details willdefinitely appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

0 The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of this speci- 35 fication, in which the figure is a side elevation view of my improvedcarbureter, a portion being shown in the vertical section to show thestructural details thereof.

Referring to the drawing, A is the air-stor- 4 age tank,'and I is anair-pump and motor.

The pump is connected to the storage-tank A by a pipe I. The pipe I isprovided with a suitable check-valve 2'. A delivery-pipe A is alsoprovided with a valve a, located in front of the press u rc-regulator A,and a check-valve (6, located beyond the regulator. A reservoir B forthe liquid hydrocarbon is provided. The

reservoir B is supported in an elevated position with reference to thecarbureter proper 5 and is provided with an oil-delivery pipe 6.

A pipe I), which is connected to the air-delivery pipe A beyond thepressure-regulator thereof, opens into the storage-reservoir above theoil-level thereof. The object or this con? nection will appear later. Asuitable valve b is provided for the pipe I). These parts areillustrated in conventional form.

The air-delivery pipe A and the oil-delivery pipe o open into avalve-chamber 0. Supported within this chamber on the pivoted le- 6 Ver0 is a downwardly-opening lid-valve 0 for the air-delivery pipe. Thevalve 0 is adapted to be opened by the passage of air therethrough. Thedelivery of the oil from the reservoir B is controlled by the valve 0.The 0 5 valve 0 is provided with a downwardly-projecting stem adapted torest on-the lever 0. Thus arranged the air-valve 0 opens downwardly andthe oil-valve 0 opens upwardly, so that both valves are open at the sametime. 7 The lever c" is suitably balanced, so that the valves arenormally closed.

The carbureter consists of the chamber D and the vertical tube E, whichis connected to the valve-chamber C and to the top of the 7-5 chamber D.The chamber D is provided with horizontally-arranged baflie-plates inthe upper portions thereof. The baflEl'e-plates cl are oppositelyarranged within the chamber D,

thereby forming a zigzag passage therethrough. A packing d, of suitablewicking or absorbent, is arranged between the bafHeplates. The tube E isprovided with a plurality of foraminated partition-plates 0. Theseplates are concave in shape and are arranged 5 alternatelythat 'is, eachalternate plate is arranged with its concave side up and the remainingplates are arranged with their concave side down. Thus arranged, thetendency is to spread the oil over the plates, which in- 9 sures athorough contact of the air therewith. The service or delivery pipe F isprovided with a pressure-regulator F. A- mercuryregulator f ispreferably located beyond the regulator F as a further means of insuringa steady deliveryof the gas. A suitable checkvalve is provided for theservice-pipe F. This check-valve is located in front of the regulator F.

The pressure-regulators A and F are set '1 t 15 aliJ at about the samepoint, so that when the pressure in the carburetor is relieved by drawing gas from the service-pipe air is admitted. The incoming air opensthe valve 0, and this through the connections described opens theoil-valve 0, so that the air and oil are admitted together. The valve 0is so shaped that the amount of oil admitted therethrough is in properproportion to the amount of air admitted. \V hen the pressure in thecarbureter again reaches the predetermined point, the passage of airthrough the valve 0 ceases, and the valves are automatically closed, thepressure of the oil assisting in closing the same. In passing throughthe plates 6 the oil and air are thoroughly mixed. Should any surplusoil reach the chamber D, it is absorbed by the wickin g material (Z, andis thus brought in contact with the air passing therethrough. Thisinsures a complete utilization of practically all the oil passing intothe carbureter. A pressure equal to that in the carbureter is maintainedin the oil-reservoir by means of the pipe 7/, so that the oil readilyflows from the oil-reservoir into the carbureter by gravity. With theparts thus arranged the amount of oil admitted is properly proportionedto the amount of air admitted, and this is governed by the amount ofcarburcted air or gas drawn from the service-pipes.

My improved carbureter is simple and compact in structure, yet is oflarge capacity, is very economical to use, and is not likely to get outof repair. I have described and illustrated the same in the formpreferred by me on account of its simplicity. 1 am, however, aware thatit is capable of structural variation without departing from myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
